When converting a decimal to a percent, move the decimal point 2 places to the right then add a percent sign.

   1) .87 = 87%

When converting a mixed number to a percent you must first make it an improper fraction.  To convert a mixed number to an improper fraction you  First: Multiply the denominator (bottom number of fraction) by the whole number.  Second: Add the numerator (top number of fraction) to that product.  This number is your new numerator for your improper fraction.  Last: The denominator stays the same.

    2) 4 and 5/10

            10x4= 40

            40+5= 45 ----This is your new numerator

 So your improper fraction is 45/10 which can be reduced to 9/2

Then take your improper fraction and divide the denominator into the numerator. 9/2= 4.5  Then you can use the steps from above to turn the decimal into a percent.  Your percentage for #2 would be 450%

3) Use the steps listed above for converting an improper fraction to a decimal then to a percent.

    23/25 = .92

    .92= 92%

1) Change 0. 87 into a proper fraction, which is 87/100. Then x100 to get 87%

2) Convert the mixed number into an improper fraction which is 45/10. Multiply x100 to get 450%

3) Multiply 23/25 by x100 to get 92%
